<h3><u>Answer;</u></h3>
C) Covalent bonds are generally weaker than ionic bonds because they overlap electrons to fill their outer shell.
<h3><u>Explanation;</u></h3>
- <em><u>Covalent bond is a type of bond that results from the sharing of electrons between two non-metal atoms. </u></em>
- <em><u>Ionic bond on the other is a type of bond that results from the transfer of electrons between metal atoms and non metal atoms, where a metal atom looses electrons and a non-metal atom gains electrons.</u></em>
- <em><u>The amount of energy required to break an given bond determines how strong a particular bond is.</u></em> Ionic bonds require more energy to break as compared to covalent bond and therefore they are stronger than the covalent bonds.
The offspring can have some features for the parents relatives and can look nothing like the parents. They can look exactly alike to more of one parent then the other or have features from both parents as well

Answer:
A. 16.67 m/s
Explanation:
Speed or velocity refers to the rate of change in distance over a change in time. That is;
Speed = Distance ÷ time
Where;
Speed is in metre/seconds
Distance is in metre
Time is in seconds.
In this question, Steve throws a football 50 meters in 3 seconds. The average speed can be calculated this:
S = D/t
Where; d = 50m, t = 3s
S = 50/3
S = 16.6666666
S = 16.67m/s
Number 13 is D the heart has 4 chambers and pumps blood to the arteries and number 14 us C
carbon-12 and carbon-14 are differed by the neutrons count in their atoms.
<u>Explanation:</u>
The two isotopes of the carbon element are carbon-12 and 14 . The difference between them is the neutrons count in each of their atoms. This is how it works. The digit after the atom's name represents the protons and neutrons count in the atom or ion. The atoms of both carbon isotopes have 6 protons. carbon-12 atoms comprise with 6 neutrons, whereas 8 neutrons in carbon-14.
A neutral atom usually have the same counts of electron and proton, so that a neutral carbon-12 or 14 atom have 6 electrons. Although neutrons do not possess any electric charge, their mass is similar to that of protons, so different isotopes consist different atomic masses. Carbon-12 seems to be more lighter when compared with carbon-14.
